Questions, answered
Know what you are buying.
Is Viewer really free?
Yes. Viewer remains free without registration or a time limit. It supports local Parquet and CSV, single-source queries, two tabs, current-page CSV export, offline verification examples, and report reading. BigdataSight 1.2 also provides local command-line and AI queries within Viewer limits.
Does BigdataSight include an AI assistant?
Connect a compatible external AI client through MCP. That client supplies the assistant and may require its own account or plan. BigdataSight provides data tools and processes queries on your Mac; information returned to the client is handled according to its provider and settings. See the AI setup guide.
Can I use it from Terminal?
Yes. BigdataSight 1.2 includes the bds command line. Install it from Command Line → Set Up bds… in the app, or copy a SQL query using Run → Copy as Command…. See the command-line quick start.

No. Pro is a one-time purchase that permanently unlocks the currently delivered Pro capabilities. Current product updates are included.
